How does something that takes in co2 and off puts pure oxygen, equate to depleated oxygen?You are correct about the cost of UV sterilizers. Plants will work for a lightly stocked pond but most people keep more than a few oversized fish. Plants actually clog filtration and too much plants can actually deplete the water of oxygen. Great tip on the balance of the ecosystem.
They do make UV for lakes.

just use bullfrog tadpoles. im not 100% sure its gonna work. but I only heard they eat algae. just feed them ground up flakes and sadly they will grow to frogs. ur koi will eat the eggs to controll their population.
